Where collection is allowed
American Fossil expressly sells visitor access to its DigFish quarry and states that guests may keep fossils found under the quarry terms.
The quarry limits the number of guests. Booking is the reliable way to secure space, even when walk-ins are accepted; use only the operator’s directions.
Tools, limits, and timing
Tools and methods
Use the quarry’s supplied or approved splitting tools and staff method. Do not enter operating areas or remove material that has not been assigned to the visitor dig.
Amount and use
The current operator terms govern keep privileges, exceptional finds, rescheduling, and no-shows. Review them during booking rather than relying on an older summary.
Season and current status
Seasonal and weather-sensitive. Confirm current dates, hours, rates, capacity, and directions at booking.
Rules to confirm at the site
- Book ahead when possible.
- Check in before handling shale.
- Work only in the visitor dig area.
- Show complete, rare, or unusual vertebrate material to staff.
An old webpage, saved map, app layer, social post, or prior visit cannot override a current closure, posted boundary, permit condition, mining claim, staff instruction, or landowner decision.
What makes the site geologically useful
Thin-bedded Green River Formation limestone preserves fish and other organisms from an Eocene lake system.
Part and counterpart, bone alignment, and fine detail should be protected during splitting and transport.
